A new magazine scan features Cless Alvein from Tales of Phantasia and Stahn Aileron from Tales of Destiny as cameos in Tales of Xillia 2's arena.
I'm not sure if Rutee can be fought too, but so far she's only been shown as part of a side quest. It could be possible that you can fight her, though.
Also, some people in Japan already have their copies of Tales of Xillia 2, so as much as possible, we won't be posting any "news" (i.e. info from playthroughs) about the game much.
For the rest of us, only a couple of days left until the game's release! I've been checking some playthroughs of Xillia 2, and so far the game's looking pretty good. It's actually way better than I expected, story-wise. Anyway, if you haven't ordered the game yet, check out the links below.
